About this product
The sheet gives all four times at three temperatures, so the same coat of zinc takes 2 days to cure at 30°C and 5 days at 10°C. This page uses the 20°C column.
Using this specific product
Rust-Oleum Cold Galvanizing Compound 1085 is listed here as the Zinc-rich coating with a three-temperature table (UK) version for steel and galvanizing touch-up. For treating rusted metal, the useful question is not simply whether the surface looks finished—it is whether the exact next-action milestone shown above has been reached.
Before you start
- Confirm the package says Zinc-rich coating with a three-temperature table (UK); related versions can use different timing.
- For steel and galvanizing touch-up, pay particular attention to loose rust removal, film thickness, temperature and humidity.
- At 10°C and 60% humidity it is 30 minutes. At 30°C and 50% it is 15 minutes. At 10°C it is 4 hours. At 30°C it is 1 hour. At 10°C it is 8 hours. At 30°C it is 3 hours. At 10°C it is 5 days. At 30°C it is 2 days.
How to check readiness
Confirm the surface is dry and the converter has changed color before topcoating. Touch only a hidden edge first; a dry surface can conceal a soft layer underneath. Lift or move the item gently and avoid twisting the bond or pressing finished faces together. Before recoating, confirm the first coat matches the manufacturer’s stated condition; if the maximum window passed, check whether sanding is required.
Avoid this mistake
Topcoat timing depends on the topcoat type; check the stated recoat window.
